Trans temp sending unit

[Rnpeder]

I have a '95 auto CTD. I am about to install the trans temp gauge. I have read alot of threads and have read that mine has a fitting on the line. My question is where? Is it the same fitting that the stock sensor fits into? Can you unhook the stock sensor without any problems?

 

[HoleshotHolset]

If you unhook the stock sensor you will need to put a 7k ohm (??I think this is the right value for the resistor... ??) resistor so that the transmission temp light doesn't come on, and so that your transmission behaves properly as far as OD and TCC.

Besides what Matt said you have two other alternatives. You can cut the trans output line to the cooler and add a tee, not recommended because of potential leaks. Other choice, which I did, is to install your sensor in the second from front test port passenger side of transmission. The sender must not be longer than 2" inside the trans or it will interfere with the workings of the transmission.

trans temp guage

Illflem, I was interested in the reply you posted on the site. You mentioned you mounted your sending unit for the temp guage in the second port back from the front, passenge side; this is the accumulator port correct? Isn't there a plastic piston/spring assembly in there for cushioning the shifts? I bought an AutoMeter with the electric sending unit, but have been stimied as to where to install it, as my '96 doesn't have the temp sensor in the outlet line. The accumulator sounds attractive, but I sure don't want to interfer with the operation.



Thanks for the info in advance.

SR, I thought it was just a test port, but I'm no AT expert. I installed mine there at the advice of Bill Kondolay. I would rather keep the stock temp sender functions intact and not cut into lines.

You should have the OEM transmission temp sensor for the warning light in the transmission cooler line to the heat exchanger. Remove the OEM sensor, install a pipe "T" (got my T and adapters from Home Depot) and reinstall the OEM sensor and the new sensor for your gage in either end of the "T". This retains the 'trans. hot' feature on you dash. No resistor required. "T" and pipe adapers from H/D cost all of $3. 00.

Hope this helps.

For 96 model trucks you can get the 95 output line and then you use the "stock" port for the 95 for the sensor as the 96 has it mounted elsewhere. I think the line is about $100.

trans temp sender

If Bill Kondolay said to put the sensor in the accumulator port, then that's a good spot, as he is VERY knowledgeable on the Dodge autos. My sensor is about the length of a water temp sensor; does this sound about like what you have? (Illflem)

My '96 doesn't have the the sensor in the cooler line, I believe it is intergal with the governer pressure sensor, inside the trans. Nice place to hide it isn't it.



I've had the complete pressure line side replaced with the upgraded lines, so I'm not real eager to discard them if the accumulator port will work. The 95's then have the sensor in the lines?



Thanks to all for the great help,

SR, my sender is about an inch long from where the threads start. When I asked Bill I was specific about a '95 and so was his answer. Stock sender on '94-'95 is in the output line. Not positive but think the trans are identical in a '96 except for the sender location. I asked on his website you might want to also http://www.dieseltrans.com/DTTech/index.sht



I started out with a tee for both the stock and new senders as GMIKEP mentions. It worked fine until the outside temps were below zero, then it took quite a bit more driving for OD to engage. Using the port was easier anyways.

trans temp sender

Illflem, thanks again for the info, and I did send an e-mail off to DTT to ask about the location as you mentioned. I too think the transmissions are identical, at least in that area, so it should work. Do the temps pretty well match what would be expected on the output line? Tonight I just finished removing the check valve from the cooler line, as I have been told to remove it due to the restriction. I have had one fried trans already due to the valve sticking closed. It wasn't fun, but the thing is history!

Trans temp Sending

If my reading memory is correct, the transmission has to be in drive to get a temp reading from second port. Someone correct me if I'm wrong.

Jerry, my gauge in the second port works in N as well, doesn't in P, never checked in R, too busy watching where I'm going. Reverse can be a concern for trans overheating if you spend much time trying to jockey a 5er into a campsite due to low airflow though the cooler.

Where is the factory temp sensor on a stock '96?

 

[dalton4]

Temp Sensor

Timinator, the temp sensor (thermistor) is part of the pressure sensor that connects to the governor body on the main valve body. The sensor is immersed in transmission fluid at all times.

Srehberg, would love to know what u find out from Bill K. I also have a 1996 that is getting a set of gauges this weekend. Please post Bill K's recommendation as I am in need of some guidance too. Thank You!

 

[SRehberg]

Fish On I haven't gotten a reply back from Bill K. yet, but that's not unusual, as he gets bombarded with questions. I don't know how he responds to so many inquiries, let alone get any trans work done! If I hear, I will gladly post the response so maybe it will help others as well. It's suspose to rain here this weekend, so if it does, it'll give me an opportunity to work on the trans and I will physically look at the area for clearances. Otherwise it might be a weekend or two, as I have some house projects that need attention. If you do yours, and it works o. k. , I too would appreciate a note,



Thanks for all the help, this is a great forum!
